Description
The SA Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Features
500W peak pulse capability at 10/1000μs waveform, repetition rate (duty cycles):0.01%
VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25)) (αT:Temperature Coefficient, typical value is 0.1%)
